Can the DC fan speed be adjusted?1

Often customers ask whether the DC fan speed can be adjusted? Is there anything on the fan that can be adjusted at will? The speed control function is one of the main differences between the DC fan and the AC fan, but it depends on how to adjust and how to adjust it. It is mainly related to the matching of the client. The DC fan itself is a fixed motor and will not change. When the external conditions change, the speed of the DC fan can change accordingly. For example, PWM adjusts the speed according to the high and low frequency, the most commonly used is the computer CPU fan. If you change the input voltage of a DC DC fan, the most common is the handheld DC DC fan. The DC DC fan can be customized with different high and low speeds according to customer requirements. Some people say that AC fans can also be used, but the AC fans are only at a small float. The speed is adjusted internally, and the DC fan has a very large adjustment float, 10% of the small speed, up to 100%. The cost of high and low speeds may also vary several times.
